SPECIFICATION forming part of Letters Patent No. 371,896, dated October 18, 1887.

Application filed December 18, 1886. Serial No.221,97-2. (No model.)

.To all whom may concern;

Be it known that I, WiLLIAiu B. Moolen, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in receptacles for containing compounds or compositions for preventing incrustations in steam-'boilers and in devices used in connection with said receptacle for automatically feeding said composition, when dissolved, to the water in the boiler in the proportion in which it may be required, of which the following is a specication.

My invention has relation to and consists of certain improvements in the receptacle and devices for preventing incrustations in steam boilers described and shown in the specification forming a part of Letters Patent No. 293,172, issued to Edward J. Hoffman and others on February 5, 1884. The interior of the receptacle described in said specification, and of which this is an improvement, is divided longitudinally into compartments, which contain the n'on-inorustatiug compound,which compound as it is gradually dissolved is fedl to the water of the boiler by the ends of a coiled spring and by the projecting ends of twisted wires through apertures in the ends of the receptacle. This form of constructing the receptacle and method of feeding the conipound to the water experience has show-n to be imperfect and its working unsatisfactory. No means were provided `for protecting the orifices through which the feed is made from the compound, which, being ofa gummy nature, soon clogged said oriiices and rendered the feed irregular.

My improvements consist in removing from said receptacle the diaphragms dividing the same into several chambers or compartments and dispensing with the coiled spring and twisted wires, and in inserting two or more small tubes, which, preferably, are placed against the inner side of the receptacle opposite each other, and are soldered thereto. These tubes extend from the bottom of the receptacle to Within a very short distance of the 4top or cover, and are closed at the bottom and soldered to the bottom of the receptacle, and are open at the top. Small orifices are made in the bottom of the receptacle into the tubes,

and also through the cover above the tubes, through which a wire is passed.

In the drawings, Figure 1 represents a sec tion of a steam-boiler with said receptacle susn pended in the water from one of the boilertubes. Fig. 2 is a longitudinal sectional view of said receptacle with myimprovement shown therein. Fig. 3 is an end view showing a portion of the cap broken away.

Referring to said drawings, A is the receptacle.

B B are the tubes secured therein, as above described.

C is a wire passing through the orifices a a and a e into thc tubes B B, and extending through the same and forming a loop on either end of the receptacle.

G is the non-incrustating compound.

F is a ltering material of curled shavings or some other suitable material placed over the top of the non-incrustating compound.

E E are the boiler-tubes, and c c are wires by which the receptacle is suspended in the water.

The method of using my improved receptacle and its operation are as follows: The receptacle is filled with the non-incrustating compound G to within about an inch of the top. The space above the compound and the cover f is then lled with some suitable material-such as curled shavings--which will act as a filter for the compound when it liqueties. The wire C isthen passedthrough the orices a a in the bottom of the receptacle, and up through the tubes through the orifices a a in the cover. The cover is then soldered lfast on the can, and the wires looped over the same and the ends twisted together. rlhe case as thus prepared is passed through the hand-holev or man-hole in the boiler and suspended by wires or hooksfrom one of the boiler-tubes.

To obtain the most satisfactory results the receptacle should be suspended in the water near the front of the boiler, with the bottom of the case nearest the front of the boiler and the end with the cap suspended a little lower than the bottom; The compound as it be comes liquefied by the water which passes through the orifices a a and a a into the space IOO . above the compound will be gradually fed out kby the wire C through the orifices a a.

The amount or rapidity of the feed is regulated by the space between the cap and the end of the tubes. If a rapid feed is desired, this space is made Wider than Where a slow feed is required.

I use different compounds for different Waters, and where the compound liquefies quickly I make the tube longer and the space between the end of the tube and the cap consequently less than when the compound lquees slowly.

Having nowfully described my invention, what I claim as new, and desire to secure by Letters Patent, is

` l. In areceptacle for containing compounds for preventing incrustations in steam-boilers,

and purposes and in the manner substantially as specified.

2. In devices for preventing incrustations 25 in steam-boilers, the combination of the outside case or receptacle, A, with the tubes B B and the Wire C, arranged substantially as and for theuses and purposes specified.
